• Detecting regional settings (List Separator) from web

  - by Toms Mikoss

  After having the unpleasant surprise that Comma Seperated Value (CSV) files are not necessarily comma-separated, I'm trying to find out if there is any way to detect what the regional settings list separator value is on the client machine from http request. Scenario is as follows: A user can download some data in CSV format from web site (RoR, if it matters). That CSV file is generated on the fly, sent to the user, and most of the time double-clicked and opened in MS Excel on Windows machine at the destination. Now, if the user has ',' set as the list separator, the data is properly arranged in columns, but if any other separator (';' is widely used here) is set, it all just gets thrown into a single column. So, is there any way to detect what separator is used on the client machine, and generate the file accordingly? I have a sinking feeling that it is not, but I'd like to be sure before I pass the 'can't be done, sorry' line to the customer :)

• Can't write text into textbox in ASP.NET web app

  - by dotnetdev

  Hi, I have an ASP.NET web application. In the codebehind for the .ascx page (which I embed as below), I attempt to write a string to a textbox in a method like this: Code for embedding control: Control ctrl = Page.LoadControl("/RackRecable.ascx"); PlaceHolder1.Controls.Add(ctrl); Method to make string for inserting into textbox: string AppendDetails() { StringBuilder sb = new StringBuilder(); sb.Append("msg" + " " + textbox1.Text etc etc ); return sb.ToString(); } Called as (in codebehind event handler for button click): this.TextBox4.Text = AppendDetails(); I call it by using ATextBox.Text = AppendDetails (in the button click event handler). The textbox TextBox4 is in the designer file so I am confused why the text does not get written into this textbox (it is readonly and enabled). When stepping through, the textbox4 control will successfully show the text I want it to display in quick watch but not in the actual page, it won't. Any ideas? Thanks

• Are there such things as Email Hooks?

  - by viatropos

  After hearing about git commit hooks, I was thinking maybe there are such things as email hooks... Is it possible for me to build a program that says "hey, you just received an email, now run this ruby script"? Something like a GMail Web Hook. Is there anything out there like that? I mean I could build a cron thing that checked my email all the time, but maybe there's a more formal way. Looking for an online email system to do this with, not say my Mac Mail.

• Is a Service Bus a good option to communicate with multiple external servers?

  - by PFreitas

  We are developing an application that communicates, via web services or TCP/IP sockets, with multiple servers (up to 50 different external companies). Basically, the exchanged messages are the same (XML), but depending on the inputs of our application we should call 1 or more external servers. The benefits we would expect of introducing a Service Bus in the architecture would be: 1- Remove the need to manage all point-to-point configurations (all the 50 endpoints); 2- Simplify the communication layer of our application by having only one server to talk to; Is a Service Bus a good architectural option for this scenario? What is the best (simplest) Service Bus for this kind of communication? I read a few MSDN articles on Azure Service Bus Relay, but it didn’t seem to fit our needs. Am I wrong? Thanks for your help.

• continuous integration web service

  - by Josh Moore

  I am in a position where I could become a team leader of a team distributed over two countries. This team would be the tech. team for a start up company that we plan to bootstrap on limited funds. So I am trying to find out ways to minimize upfront expenses. Right now we are planning to use Java and will have a lot of junit tests. I am planing on using github for VCS and lighthouse for a bug tracker. In addition I want to add a continuous integration server but I do not know of any continuous integration servers that are offered as a web service. Does anybody know if there are continuous integration servers available in a software as a service model? P.S. if anybody knows were I can get these three services at one location that would be great to know to.

• Direct web URL to PayPal transaction

  - by tags2k

  Having implemented PayPal's Website Payments Standard, I'd like to link to the details view of a transaction from my site's back end - just a simple direct web URL to the PayPal side. I don't know why this is tricky but when I try to get it from being logged in to the PayPal system it seems very obfuscated, in this form: history.paypal.com/uk/cgi-bin/webscr?cmd=_history-details&info=[looks like some kind of GUID]&ptype=4&history_cache=[huge encoded string] I'm guessing it's by design but it's not very helpful if you want a quick way to jump to a transaction's details. I've tried the https://www.paypal.com/vst/id=1234 form (also with co.uk as I am UK-based) recommended on a few sites I saw in my search, but I am told that: The transaction ID in your link is invalid. This happens even when copying the transaction ID directly from PayPal's back-end order listing. Is there a reliable way to directly link to an order / transaction details page in PayPal?

• What is the best tool to achieve this API design?

  - by Jose Fernandez

  Our web app offers a service that allows a "Publisher" to create a website (we give them a CMS system) that is ready to provide this service to "Members" (think Shopify). We have some possible clients that wish to become "Publishers" but they already have existing websites (vbulletin, word press blog, etc) with their own user base. We wish to develop an API that would allow these "Publishers" to keep using their own websites, and embed our services into them. Our main business requirement is that once "Members" are logged into the "Publishers" existing system, they should be able to also access our website without having to log-in again OR have to create another account there. The process should be seamless to the "Member" and "Publishers" should not have to sync their user base with our system. We also want to use an existing API authentication/authorization system instead of creating our own (OAuth, OpenID, etc) What would be the best way to use OAuth to achieve this sigle-sign on design? If OAuth is not the best tool, is there any other one out there that fits our requirements?

• Blog engines for ASP.Net (maybe MVC) web sites

  - by J. Pablo Fernández

  I've built a web site on ASP.NET MVC and one little section of it should be a blog. I'm looking for a blog to integrate. In the worst case scenario it'd be a WordPress with a custom skin and RSS integration to the rest of the site. The best would be to have an ASP.NET MVC add-on, but I can live with ASP.NET WebForms. Do you have any recomendations on the engine? I've been checking out BlogEngine.Net and I'd like to have some other ideas to compare. Anything in particular you can point to regarding this integration?

• Combining a web application with another (larger).

  - by Kevin Brown

  I'm writing a web app, initially meant to be stand-alone--it's essentially a survey with user-management/authentication built on Codeigniter. The company I'm doing this for wants to merge it with their main system so that it acts like a feature, or a sub-app of their website. What is the best thing for me to do? I think I could do one of two things: Finish my application, as I had planned to initially, and let them handle the merging.It would probably save me a headache. Stop where I am in development, and migrate my authentication system to theirs, migrate the payment system to use theirs, and then finish the app. In your opinion, or experience, what is the best thing to do?

• Auto-versioning of static content with JBoss

  - by Bears will eat you

  As per the Q&A here, I'd like to implement a similar auto-versioning system for a web app running in JBoss 5. Is there anything already out there to do this sort of thing, or will I need to write something myself? To be clear: I am not using PHP. Not knowing much about PHP, I'm not sure what the Tomcat/JBoss analogs of PHP's .htaccess, etc. are. If I do have to write my own auto-versioning, where would I start? The principle is clear to me - rewriting the URL using the file's timestamp, but I don't know much about URL rewriting with JBoss/Tomcat.

• How to query data from a password protected https website using C# .NET

  - by Addie

  I'd like my application to query a csv file from a secure website. I have no experience with web programming so I'd appreciate detailed instructions. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET. The url of the site is: https://www2.emidas.com/default.asp. I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query. System.Net.WebClient Client = new WebClient(); Stream strm = Client.OpenRead("https://www3.emidas.com/users/<username>/file.csv");

• My ASP.NET page is making postback on web server and not on local host

  - by Rizwan Aaqil

  I have created a website in ASP.NET = www.vif-tech.com/BidsOnline When I am running it on Localhost using Visual Studio 2008, its running perfectly without any postback because I am using Ajax Update Panels (where data is changing constantly). But when I am running from my web server i.e. www.vif-tech.com/BidsOnline, its making postbacks every seconds. Even I tried changing connection string on my localhost and tried connecting to main database (not on my localhost), it's still making postbacks. Is there some error in my DB or page ?

• Publish web application from MSBuild Script using VS2010 targets resets working directory

  - by Raoul

  I am trying to automatically publish and deploy my .Net 4 web application automatically from a build script to be run by our continuous integration server. I am using the new _WPPCopyWebApplication target from VS2010 to perform the publish, however it appears to reset the current working directory of the msbuild project to c:\ this causes my prebuild steps to fail as they have relative paths to some external tools. The task I am running from our master.build file is as follows: <Target Name="PublishWeb"> <MSBuild Projects="$(ProjectPath)" Targets="ResolveReferences;_WPPCopyWebApplication" Properties="WebProjectOutputDir=$(DeployPath);OutDir=$(TempOutputFolder)$(WebOutputFolder)\;OutputPath=$(ProjectPath)\bin\Debug;" /> </Target> This does not happen when using the legacy _CopyWebApplication. Does anyone have any idea how to resolve this problem?

• fHow can I get Opera speed-dial and password management features in other browsers?

  - by Howard Guo

  I heavily rely on Opera's speed dial and password management features. Lack of these two features is really stopping me from switching to another web browser such as Chrome or Firefox. Opera's password management has two unique characteristics which I rely on heavily: It saves passwords on all pages, (apparently) despite the page's meta data asking not to save passwords. It offers keyboard shortcut and button to automatically fill in username/passwords and all other fields in a login form, then automatically submit the form. How can I get those functions in other browsers? Thank you!

• Websphere exception handling

  - by Benjamin

  Hi all, From a security standpoint, what is the best solution to handle application errors with Websphere? I've been thinking of creating a class that is called every time an application error is generated, log the error and display a generic error message to the users. In PHP this can be achieved using the set_exception_handler() function. Is there something similar for websphere that could be configured in the web.xml? I've found codes like this on the internet: <error-page> <error-code>500</error-code> <location>/servlet/ExceptionHandlerServlet</location> </error-page> But that would only work with "500" HTTP error codes. I really want something generic that catches everything. Something like a class that implements a certain interface which can have access to all information about the error. Thanks for your time.

• Should I use Perl or PHP or something else for this project?

  - by Clinton

  I'm about to embark on a project that will need to: Process XML Heavy text parsing of non-xml documents Insertion of data from xml and non-xml documents into a relational DB. Present processed data to user from db using webpages. The website will be subject to short periods of very heavy loads to pages (300+ visitors a minute for several minutes), but most of the time will be idle (a dozen or so visitors a minute). The ability to cache or scale to load will be very nice. I have a very strong background in Java and web services, but I do not want to use Java for this project as I'd like to diversify my skill set. Which language would you recommend and what are some pros and cons that you might recognize from your own experiences?

• Web UI for showing like/dislike community comments side-by-side

  - by Justin Grant

  We want to add a comments/reviews feature to our website's plugin gallery, so users can not only vote up or down a particular plugin, but also leave an optional short comment about what they liked or didn't like about it. I'm looking for inspiration, ideally a good implementation elsewhere on the web which isn't annoying to end users, isn't impossibly complex to develop, and which enables users to see both good and bad comments side-by-side, like this: Like: 57 votes Dislike: 8 votes --------------------------------- -------------------------------- "great plugin, saved me hours..." "hard to install" "works well on MacOS and Ubuntu" "Broken on Windows Vista with UAC enabled" "integrates well with version 3.2" More... More... Anyone know a site which does something like this?

• Concerns with SoapUI Pro when Updating Web Services

  - by Plenoge

  This may unfortunately be a very open-ended question, but a coworker of mine has shared concerns about using SoapUI Pro as our automated regression testing tool primarily on the basis that seemingly trivial WSDL changes can cause headaches for the QA crew. My coworker's particularly concerned that if we update the WSDL, even with a name change, we'll need to touch and update each existing test. As I understand it SoapUI Pro offers a refactoring tool to handle this for you. What are your experiences with SoapUI Pro and updating your web services? Am I missing something?
